Bump for 1st part solved

Stuck on 3, 8, 10. 🤷

Bump for solved all of them

Thank you bump =)

i guess 10 is some obscure file sharing website

Stuck on 2 and 3. Unsure if 9 gives any games but I solved it.

Bump for solved!

Bumpy bump. Still stuck at 2, 5 and 10 - funnily enough, 2 and 5 aren't giving that much trouble to other people in the thread, huh...
Edit: 2 has been vanquished! so now I may as well ask: Am i looking for a tool to identify used steam keys, or is there a different way to do this?

Bump for solved.
Im just not able to reach the hidden GA's behind 8 and 10 (if any)

Bump ;)

Bump for stuck on 3. I think to know what is it for, but I don't know where to look.

bump for solved ;)

A very tired bump from me....solved......yay....my head hurts 🤣. This was quite a trip down the rabbit hole, thanks for the ride and the half metre hole in my desk from my head bashing against it for the giveaways.
I think I found all the bonus ones except for 8, I know what it is meant to be but I can't seem to get anything out of it.... I think the hole in my desk beckons me once again....😄

Without the hints, I wouldn't have made it. Thank you! :)

Still completely stumped with 10, even after searching a lot through google orz could I get a nudge in the right direction, if possible?

Loved this puzzle. Was really difficult, but with enough hints and time.
Thanks!

Bump for finally solved
